RAR-eSR-qLR-OV-LB-LS-ref-[2.7-5.5]-[0.55-3.3].07e, as any Power Management Virtual Component designed by Dolphin Design, is readily retargetable toward any submicron CMOS process in TSMC 40uLP

Key Benefits

  • The retention Alternating Regulator (RAR-eSR-qLR-OV-LB-LS-ref-[2.7-5.5]-[0.55-3.3].07e) embeds two regulator Virtual Components called eSR-Tugela-OV-LB-Bu-ref-[2.7-5.5]-[0.55-3.3].06 and qLR-Aubrey-OV-ref-[2.7-5.5]-[0.55-3.3].05.
  • Manages booting and transitions between embedded regulators.
  • Enables high power and low power operating modes.
  • Embedded power pads with ESD protection.
  • Designed with standard 3.3 V and core transistors.
  • Compliant with Maestro R1.1 (and later) (Patented solution to build Activity Control Units)
  • Integrated Local Supply Monitoring (LSM)
  • Embedded level-shifter with isolation capabilities
